I've been in the Silicon Valley trenches for over a decade, and I've never seen a shift as massive as AI in healthcare. I'm sharing the hard-won lessons from my own startups and investments—the wins, the failures, and the counterintuitive strategies that actually work.

The Framework That Actually Works

I'm going to share the exact framework I use when evaluating 7 things i learned angel investing in 20+. It's not complicated, but it requires discipline.

Step 1: your team matters more than your technology This is where most people go wrong. They skip this step entirely and jump straight to execution. Don't do that.

Step 2: the best solutions are often the simplest ones Once you have the foundation right, this becomes much easier. I've watched founders struggle with this for months when the answer was staring them in the face.

Step 3: Iterate relentlessly Nothing works perfectly the first time. The companies in my portfolio that nail 7 things i learned angel investing in 20+ are the ones that treat it as an ongoing process, not a one-time project.

Why Most Approaches Fail

Let me be direct: about 70% of the approaches I see to 7 things i learned angel investing in 20+ are fundamentally flawed. Not slightly off. Fundamentally flawed.

The root cause is usually one of three things:

  • Copying what big companies do without understanding why they do it. What works for Google doesn't work for a 10-person startup.
  • Over-engineering the solution when a simple approach would work better. I've seen teams spend six months building something that could have been done in two weeks.
  • Ignoring the human element. Technology is the easy part. Getting people to actually use it is where the real challenge lives.

This connects to broader themes around AI diagnostics, medical AI, drug discovery AI that I've been thinking about a lot lately.

Final Thoughts
